The right option is d) bubbles
The production of bubbles when baking soda mixes with an acid such as vinegar is the observation that indicated a chemical property of the baking soda.
Baking soda (also known as sodium bicarbonate) is a nonflammable, white crystalline powder. Baking soda is odorless, and alkaline. Baking soda reacts with vinegar (acetic acid) to produce carbon dioxide (a gas), water, sodium ion and acetate ion. Baking soda is used for many purposes such as; as an antacid for treating indigestion, for baking, in fire extinguishers, as a water softener, as a pesticide, and to remove dirts from materials.
I mean, there's plenty of differences between muscle and nerve cells. For one, they serve different functions. Nerve cells react and send stimuli rapidly through action potentials, functioning in the nervous system and allowing the brain to communicate with the rest of the body, while muscle cells allow muscles to move. Another difference is the structure of the cells, with nerve cells having dendrites, axons, and neurotransmitters to assist in the firing of action potentials. You're going to have to be a little more specific, I can't really help you any more with such a broad question.

trace elements are sometimes referred to as micronutrients
Endocytosis enables extensive particles to enter the cell, and exocytosis ousts vast atoms from the cell. Along these lines, the cell can acquire things it needs and disposes of things it doesn't. Exocytosis is the turn around process, where a cell ousts substantial particles, generally squander from cell forms.
